I had 3 hours on an account before it got a 2 day using this.
 

The account was several years old but fresh on OSRS, manually trained mining then went to MLM. Only some WC and FM levels on top of that manual. I'd say mine was more because the account itself than the script but unsure.

Ive never had any luck with it myself. Bought it a few months ago and lost a few accounts to it. Czar makes great scripts and cant blame him. I botted 10-20 minutes and breaked for 30-60 and still never got an account through to get coal bag so i gave up. Have many other czar scripts with no issues.

Depends how old the account is, play-time and what you was doing before hand.

I've collected over 1000+ hours of mining at MLM without any bans.
